Several complex PHP tasks on customer booking system

We are currently building our very own custom PHP customer booking system for our travel / tour company. Although we have completed the basics, we are now looking for a new developer to help us continue to build and add to the functionality and to connect to several third party API's including SendGrid and Quickbooks.

The successful developer will need to be able to speak fluently in English and their code must be clear with good commenting throughout all works - so we know what's what.

We are looking for a long term developer, someone who we can trust and work with over the next few years to keep expanded. Happy to pay per hour or for each small project.

Some examples of what will need to be completed -

- Creating bespoke reports from the data within the database and displaying them in a user friendly manner.
- Connecting to SendGrid to pull in dynamic data to several email templates, with a mixture of some being sent onClick and some depending on certain criteria.
- Creating a front end portal for our customers to login and upload required details and documents.

There is plenty of work that needs completing over the next couple of weeks and even more over the coming months and years.
